In-Memory Sessions
(SessionBasedLoadBalancing = true)
In Figure 3-5, each user has their own current session, within which more than one
request has been made. Note that all the requests from user 1 are routed to the
NSJSP process in CPU 0, which has the session object for user 1. All requests from
user 2 are routed to the NSJSP process in CPU 2, which has the session object for
user 2.
Configuring In-Memory Sessions
In the installation-specific servlet.config file located in <NSJSP_HOME>/conf,
set the value of the attribute SessionBasedLoadBalancing to true. Example 3-61
shows the Arglist from an installation-specific servlet.config file with
SessionBasedLoadBalancing enabled.
